I've never been convinced about this one and it's been nearly a year. It's still not clear what to do here. — François G. Dorais ♦ 10 hours ago

@FrançoisG.Dorais it's also unlikely that anybody might suggest anything more convincing to you if you don't say why you're not convinced. — YCor 10 hours ago

They both have tag descriptions and they don't match: one explicitly includes non-associative algebras and the other explicitly includes commutative rings. It seems somebody thinks the two are slightly different. — François G. Dorais ♦ 10 hours ago

@FrançoisG.Dorais it guess just means that these tags were written by two different persons without comparing to the other one — YCor 10 hours ago

It seems that several answers to Help cleanup tags! have been deleted recently: data.stackexchange.com/meta.mathoverflow/query/856409/…

Three post by YCor: about discrete-series chat.stackexchange.com/transcript/10243?m=47656414#47656414, about limitcycle chat.stackexchange.com/transcript/10243?m=48569459#48569459, about semigroups and monoids chat.stackexchange.com/transcript/10243?m=43037803#43037803

deleted-tag The tag discrete-series existed on several questions: chat.stackexchange.com/transcript/10243/2018/11/17 In some cases the tag is not displayed in the revision history.

Although there are a few posts where it was removed manually: data.stackexchange.com/mathoverflow/query/927958/… I do not see the tag in the deleted posts: data.stackexchange.com/math/query/883845/…

It seems that the tag limicycle was change to limit-cycles which now has 32 question.

The tags semigroup-theory, semigroups and monoids are now synonyms of the master tag semigroups-and-monoids.

The other two deleted answers were mine, one was about the tag darboux chat.stackexchange.com/transcript/10243?m=42666452#42666452 and the other one was about the synonym models-of-peano-arithmetic $\to$ models-of-pa chat.stackexchange.com/transcript/10243?m=41633145#41633145.

When I saw your question I did the bet that you would eventually, at some point, edit its tags just to add "limitcycle". It's too predictable :) — YCor Feb 18 '18 at 0:30

@YCor Yes. As you have predicted, I could not resist myself from adding this tag:) — Ali Taghavi Feb 18 '18 at 5:32

@YCor I will just add that (limitcycle) seems to be renamed to (limit-cycles). I suppose that was your suggestion on meta - although I no longer can see the post, since it was deleted. — Martin Sleziak 7 mins ago

Deletion of tag-related posts on meta was also briefly mentioned in the end of this conversation - related to the removal of the (inverse) tag: chat.stackexchange.com/rooms/10243/conversation/…

Probably the users who want to be involved in tag-related discussions are supposed to work towards 10k reputation, so that they can see deleted questions.

I actually can read the pdf from the doi link: https://link.springer.com/content/pdf/10.1007%2F978-1-4020-5764-9.pdf

Is there some reliable way to check whether this is just because I am currently somewhere with subscription or whether it will be displayed for everybody?

Could maybe tools for testing website from various locations be a way to achieve this.

For example, when I tried the url in GeoPeeker I see there "Buy eBook". (For the same link which gives me access directly to pdf.) So I can safely assume that this is behind the paywall.

Q: Noncommutative rings/algebra tags

I'm suggesting to make noncommutative-rings a synonym to noncommutative-algebra, in the same way as commutative-rings has been made to ac.commutative-algebra. Initially asked there, I'm asking it here to make it more visible. One moderator considered this request and replied that the tag descri...
